IMPROVEMENT IN FASTENERS FOR THE MEETlNG-RAlLS OF SASHES.

Specification forming part of LettersPatent N 0. 178,885., dated J time20, 1876} May 17, 1876.

To all whom it may concern Be it known that I, WARREN H. TAYLOR,- ofStamford, in the county of Fairfield and State ofConnecticut,'haveinvented certain new and useful Improvements in SashFa'sts or Locks, of which the following is a full, clear, and exactdescription, which will enable others skilled in the art to make and usethe same.

The object of my invention is to construct a sash-lock which, whilesusceptible of convenient operation from the inside of thewindow, cannotbe unlocked by means of any instrument introduced between themeeting-rails of the sashes; and my invention essentially consists ofthe combination of a tubular post adapted, by means of a suitablebase-plate, to be attached to, and supported on, one of the meeting-rails of the sashes to be locked; a locking arm or lever pivoted uponsaid post, and a vertical reciprocating shaft-spindle working in saidtubular post, by the automatic elevation of which spindle it is causedto engage with and lock the turning-arm to the post,

while by the depression of the spindle the arm may be released, and leftfree to be turned, as will hereinafter more fullybe set forth.

In the accompanying sheet of drawings,

making part of this specification, Figure l is a top view of myinvention 5 Fig. 2, an elevation of the same, partly in section, on line1 1 ofyFig. 1; Fig. 3, an elevation, partly in section, of the lockingarm or lever; and Fig. 4, a bottom plan of the same, partly in section,

on line 2 of Fig. 2.

A represents the locking arm or lever turn-' ing upon a central hollowpost or pivot, '13, rising from the plate 0, the hookedend a of whicharm engages with a suitable post or catch, 1), rising from the plate 1).The lower part of the post B is bored or otherwise formed to present asmaller opening than that in its main portion to receive the shaft orspindle E, fitted to the outer or upper end of which is the removablehead or button F, and beneath this the spiral spring G, pressing on theunder side of the button F, and upon the flange or shoulder around thesmallopening, tending always to elevate the button F and shaft orspindle E. The lower end of the spindle E-is provided with a wing orteat, e; and in the lower part of the base or hub of the revolvingapplication filed arm A are two sockets or recesses, w m, with whichsaid wing is adapted to engage, being held in such engagement by theupward pressure of the sprin g G. In the lower part of the boss B is acavity corresponding in form to the shape of the wing 6, into which thelatter is fitted, thus preventing the rotation of the wing e and spindleE. Now, it is obvious that when the wing e engages with either of thenotches x w of the turning arm A, as shown in Fig.2, it looks the latterinto engagement with the post B and plate 0, and prevents the rotationof the arm A on its center. The two notches m :r are at a right angle toone another, and so located as to secure the arm A either in theposition shown in Fig. l,when it is locked, or in a position at rightangles thereto when it is unlocked. To release the arm A for thepurpose'of looking or unlocking my improved sash-fast it is onlynecessary to depress the button F with the finger, thus liberating thewing e from engagement with the notch 00,

,when the arm A will be free to turn on its center for either locking orunlocking, as desired,

by the automatic engagementof the wingsewith of the locking-spindle andits wing, as well'as guard against accidents which might arise fromturning the locking-lever too far round, its hub is provided with arecess or guideway for the wing e, of a depth less than that of thenotches 00 m, and extending between them, as shown in Figs. 3 and 4:;and the downward movement of the spindle is limited either by thecompression of the spring G, or, as herein shown, by the end of thespindle coming in contact with the upper surface of the sashrail. Thedownward movement thus allowed is sufficient to carry the spindle-wingbelow the guideway, but not below the general level of the bottom orbase of the lever-hub. Thus,

y i FICE. A

the movement of the lever-hub over the wing extendsonly from notch tonotch by way of the recess or guideway between them, allowing the leverto turn one-fourth of a complete revolution, and. be automaticallylocked at each end of its movement.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

1. The combination, in a sash-lock,,of the tubular post B, the turninglocking arm on lever A, pivoted upon said post,,and having no verticalmovement, and the shaft or spindle fitting in the tubular postconstantly engaging therewith, moving vertically only, and

adapted'to be engaged with, and disengagedv from, the lever,substantially as hereinbefore set forth.

2. The combination, substantially as herein befor'e set forth, of thetubular post B, adapted for attachment to a sashrail, the locking arm orlever A pivoted upon said post, and having notches a: in its base,theshaft or spindie E, moving vertically in the tubular post,

its wing e, and the spring G, whereby thellever is automaticallyfastened in the locked or unlocked position by theengagement of thespindle-wing a with its notches m, and is left free to turn a partialrevolution by the depression of the shaft or spindle, asset forth. Intestimony whereof Ivhave hereunto subscribed my name.
